The 3 combo pieces

How to execute it

  1. Cast Donate by paying {2}{U}, giving control of Colfenor's Plans to an opponent.
  2. Whenever the opponent that controls Colfenor's Plans casts a spell from their hand, Knowledge Pool triggers, exiling that spell.
  3. Because Colfenor's Plans prevents the opponent from casting more than one spell each turn, the opponent cannot cast the spell permitted by Knowledge Pool, or any other spell that turn.

What the combo produces
